Abstract: PURPOSE:To detect the invalidity of an address even if a displacement address is designated beyond the upper limit of an assigned area, by detecting the invalidity of address by an address converting mechanism. CONSTITUTION:A processing program 1 issues an assignment request indicating the size of a required area to an area control program 2, and the area control program 2 refers to a page table 3 to determine assignable virtual pages and reports them to the processing program.

Title: Electronic gas governor device
Inventor: MORI KEIICHI
IPC: F23N1/00
Filed: 1982-04-12
Abstract: PURPOSE:To perform a precise setting of a gas pressure over a wide range to prevent leakag of gas, by a method wherein the pressure of a gas pressure sensor is held in a set pressure by means of an electronic control circuit for driving and controlling a proportioning control valve in accordance with a signal from the gas pressure sensor. CONSTITUTION:A gas proportioning control valve 16 is located in a gas path leading to a burner 3 from a gas inlet 1, the gas pressure of the burner 3 is detected by a pressure sensor 17, and the proportioning valve 16 is controlled by a control circuit 18 so that the pressure is kept constant. When a main gas pressure increase, a pressure of a pressure sensor 17 rises, and the sensor 17 is increased in a resistance to provide an increased potential eb. Since an operational amplifier 32 is an inversion amplifying circuit, an electric potential ec is lowered by an electric potential by which electric potentials eb-ea are amplified at an amplifying rate in a ratio between resistors 34 and 33. As a result, a current value flowing to the proportioning valve 16 is also reduced to throttle a gas flow rate, and the pressure sensor 17 operates for the restoration to the original gas pressure.

Title: Knocking sensor
Inventor: TAKAHASHI JIYUHEI
IPC: G01H1/00
Filed: 1982-04-12
Abstract: PURPOSE:To provide large Q damping amount, reduced dispersion in a resonant frequency, and easy adjustment of the resonant frequency, to prevent short circuit, and to make the wire breakdown hard to occur, by attaching piezoelectric ceramic material to both sides of a metal vibrating plate wherein two or more holes are formed so that the polarities of the ceramic materials are directed in the same direction, and electrically connecting the ceramic materials in parallel. CONSTITUTION:Two sheets of the piezoelectric ceramic materials 10a and 10b are connected in parallel. Then the electrostatic capacity is doubled and the Q damping amount can be increased. When the thickness of the ceramic material is made thin, the electrostatic capacity is further increased. Since the resonant frequency is determined by the interval between the holes 9a and 9b, the dispersion in the resonant frequency becomes small. The diameters of the holes 9a and 9b are changed when the resonant frequency is adjusted. Therefore the short circuit due to flash can be prevented. Connected area is made large by providing metal foils 13 and 14 on silver electrodes 11 and 12. Therefore thin wires 15 and 16 do not become small because of the heat that is yielded when the thin wire 15 and 16 are soldered to the metal foils 13 and 14. Therefore the wire breakdown does not occur. A numeral 19 denotes a resistor, whose one end is connected to a substrate 17. The other end thereof is connected to the thin wires 15 and 16.

Filed: 1982-04-15
Abstract: PURPOSE:To obtain a tracking error signal, by demodulating and calculating four AFM signals which are supplied and recorded on the 1st and 2nd video tracks that form a frame so that the left and right stereo signals are replaced with each other for each frame. CONSTITUTION:Four AFM signals f1R-f4L obtained by giving modulation to four carrier frequencies f1-f4 with left and right stereo signals L and R are recorded on video tracks A and B together with a color signal and a recording video signal. In this case, the signals L and R are replaced with each other for each frame. When a track A2 is reproduced by a rotary head (a), the signals f1R and f3L pass through BPF2 and 4 to produce signals AR and AL which show the right and left stereo signals through tdemodulators 5 and 7. If the head (a) is deflected toward a track B1, the signals f2R and f4L have crosstalk to reproduce a signal BR. Therefore it is possible to detect a tracking error signal by a detecting circuit comprising differential amplifiers 9 and 11.

Abstract: PURPOSE:To prevent the formation of a clearance between an internal resin and an external resin by forming an optical path between a light-emitting element and a light-receiving element by a polyimide group resin and shaping the outside of the optical path by an epoxy group resin. CONSTITUTION:A light-emitting element 2 and a light-receiving element 1 are die-bonded and wire-bonded on lead frames, an optical path between the light- emitting element and the light-receiving element is formed by using a polyimide group resin 3, and these elements and lead frames are transfer-mold shaped by an epoxy resin 4.
